Dec 11, 2020 The Kilohearts Carve EQ is a 31-band EQ with built-in spectral analysis and a Match tool that makes it both addictive and useful. Carve EQ can be both heavy handed and precise, depending on how you use it. We prefer to use Carve EQ for drastic cuts and boosts. The UI also lends itself incredibly well to a fast paced production style.

Spectrum analyzer and 31 band equalizer with Auto EQ

KiloHearts has released the Carve EQ, a new 31-band equalizer plugin, which wants to assert itself as a versatile plugin for sound design, mixing and mastering. The graphic equalizer with a freely scalable surface is equipped with an analyzer that visually displays in the background a detailed view of the frequency spectrum. 31 Band 1/3 Octave Master EQ Low CPU Usage 31 Band EQ (1.17 MB). Eq31 is one such tool and, as its name suggests, it is a 31-band equalizer that brings a decent set of adjustments that cover a respectable range of frequencies. Suitable for any host (software). KiloHearts has released the Carve EQ, a new 31-band equalizer plugin, which wants to assert itself as a versatile plugin for sound design, mixing and mastering. The graphic equalizer with a freely scalable surface is equipped with an analyzer that visually displays in the background a detailed view of the frequency spectrum.

ThirtyOne MK2 is a plugin that includes a spectrum analyzer and a graphic equalizer, both have the standard 31 one third octave bands.

This pair of tools is very common in every rack of any live mixer as the final tool in the master bus, for this reason we decided to recreate the behaviour and specific time response of a very common Italian analog spectrum analyzer.

The equalizer is also inspired by analog units allowing ThirtyOne to recreate that master chain feeling that you are used to.

We put a great care in recreating the smooth lighting of LEDs driven by a smoothly increasing current flow, each column of twelve LEDs comes after a 20dB/octave filter (like the original hardware unit) and it’s response speed is selectable between 0.25, 1 or 4 seconds allowing you to see both fast peaks and average frequency level.

Each of the LED of the bar can have a value of 1, 2 or 3 dBs (like in the original hardware unit) and we also added 6dB/LED option, when changing the resolution the scale on the left of the LED display updates accordingly.

We also added a maximum peak hold LED for each frequency band that can be enabled or disabled that the original unit did not have.

Right below the spectrum analyzer we have put the 31 sliders that will let you shape the output and fix any particular resonance. Each of the sliders drives a standard 1/3 octave second order filter and can be adjusted from -15 to +15 dB, you can also change the value for each band typing in the box below each slider.

The equalizer has a very special feature called the “Auto EQ”, when enabled the output of the spectrum analyzer is used to tune the gain for each of the EQ band allowing the equalizer to automatic set itself so that the maximum harmonic balance is achieved.

ThirtyOne MK2 provides three different “Auto EQ”algorithms: Average, Median and Lucky, the first two are based on some mathematical models while the third one is a lucky mistake and we decided to keep it because it sounded good 😀

“Auto EQ” is linked to the frequency analyzer output so changing the analysis speed affects the algorithm, using the 0.25s changes the equalization very fast and allows you to track also the fast frequency spikes, while using the 4s setting works more on the average frequency content.

To tune the “Auto EQ” output you can use what we call a “compensation curve” which is an offset that it’s applied to every level computed by the “Auto EQ”, so if you think that the resulting eq curve it’s too extreme in some band you can correct it using the “custom” setting of the compensation curve. If you find a compensation curve that you like you can export it and then load it in other projects using the “load” and “save” buttons.

The resulting EQ curve can be decreased or increased using the “EQ Amount” knob that scales every gain computed by the “Auto EQ” algorithm by a fixed value and allows you to increase or reduce the level of each band while maintaining the same ratio between them.

Demo limitation

The demo is fully functional except for the fact that every now and then it will silence out, you cannot save parameter values with your session and the plugin will not respond to automation coming from the host.

EQ is one of the most basic—and important—tools you have as an audio engineer.

But there are so many different EQs out there, how do you know which ones are for you?

You might be thinking your DAW’s channel EQ is perfectly fine. But not all EQs are the same. There’s more types than you might think.

Here’s the 15 best EQ Plugins on the market today:

This article will teach you about the common styles of EQ and how to use them to shape the perfect sound.

Let’s dive in!

Analog EQ

Early EQs were all analog. Some of the earliest equalizer designs are still around today.

Engineers covet these analog beauties for the musically pleasing way they shape sounds. The musical qualities are the result of the unique circuit design of each unit.

Certain EQs became so sought after that plugin designers developed software to emulate them as closely as possible in the digital domain—leading to a mind-boggling ocean of plugin choices.

So what are the different styles of analog EQ? How do they work? What are they used for and where do they work best?

There’s no hard and fast rules when it comes to choosing an EQ. But there are some helpful guidelines that will help you get started with the classic designs.

Pultec-style EQ

The Pultec EQP-1A is the most sought after EQ ever. Well-preserved original units can sell for over $10,000.

The Pultec EQP-1A is the most sought after EQ ever.

31 band eq frequencies

Fortunately for us, the EQP-1A has a long history of software emulation. Today’s Pultec-style plugins can sound good—if you know how to use them.

Pultec-style EQ can work wonders to subtly boost top end or extend lows. It can even make broad EQ enhancements without sacrificing any of the original vibe of the sound.

Since the EQP-1A hails from the earliest era of equalizers, it’s control scheme is a little less intuitive than modern designs.

The bandwidth control affects both the high and low band, but low band works differently from the high band.

For the low band, the boost and attenuate knobs are both linked to one of four frequency options. This quirk allows you to both boost and cut at the selected frequency.

The overlapping filters create a steep bump that’s fantastic for boosting the fundamental frequencies of low end instruments.

The high band has separate frequency options for boosting and cutting with overlaps at 5 and 10 kHz.

These controls are interactive and can result in some unique equalization curves.

SSL Channel EQ

SSL console strips did a lot to inform our idea of what a modern EQ is.

SSL console strips did a lot to inform our idea of what a modern EQ is.

Classic features we’re familiar with today like integrated high/low-pass filters and variable Q were popularized by these consoles.

The SSL consoles are famous for their incredibly powerful filters.

The sharp high/low-pass filters, precise frequency ranges and extremely narrow Q options make this a EQ a first choice for surgical suturing and dramatic tonal changes. Their character is precise but aggressive.

Pro Plugin: SSL Native Channel Strip

SSL recently jumped into the software game with its own line of plugins—including an in-house version of their classic console channel strip. Why not go straight to the source?

API-style EQ

Experienced engineers often refer to API as the “American” sound in contrast to the “British” Neve tone.

They’re two sides of the same classic console coin.

If you’re a fan of music from the 60’s and 70’s, there’s a good chance some of your favourite records were recorded one of these desks.

The classic API EQ comes in a three band (550a) or four-band (550b) flavour.

The bands don’t have individual Q controls, but the EQ is designed so that the Q becomes progressively sharper as you apply more extreme cuts or boosts.

It’s intuitive and keeps you from worrying too much about the Q setting.

API-style EQ splits the difference between surgical and sculpting. Mild settings can be very transparent, while extreme cuts or boosts can be dramatic and vibey.


Free Plugin: Bee-Happy 550

Bee-Happy 500 is a free API-style plugin for those looking to start with classic 70’s console EQ.

Cheap Plugin: Sly-Fi Axis

Sly-Fi Axis is part of the UBK family of products that includes the innovative Kush Audio hardware and software. This EQ is an API on steroids that’s meant to exaggerate the analog colouration of the original.

Pro Plugin: Waves 550a & 550b

Waves 550a and 550b are fantastic native emulations of the API EQ. These are great-sounding and versatile plugins to get the API sound on your tracks.

Neve-style EQ

Neve consoles are the world’s most prized vintage recording equipment.

From the early sixties until the mid-eighties, Neve Electronics produced consoles legendary for their warm, musical sound.

The preamp section of the Neve console strip often gets the most attention, but the EQ is a big part of the Neve sound.

Neve EQs are another great option for broad, smooth cuts and boosts with lots of character.

Neve EQs are another great option for broad, smooth cuts and boosts with lots of character.

There are several different flavours of Neve EQ from the various revisions of the console, but they mostly share the same architecture with a high-pass filter, two or three parametric mid bands and one fixed high band.

The fixed 12 kHz high band found on the Neve 1073 EQ is famous for its ability to add air to vocals, drum rooms and overheads.

Digital EQ

We all drool over the analog EQ beauties. But that doesn’t mean there aren’t extremely useful and creative tools that don’t have anything in common with the classics.

Digital EQ is essential for any DAW. It’s the most precise tool in your EQ tool box.


Reach for digital EQ when you want to make changes without colouring your sound at all. In the right hands, digital EQ can be powerful, flexible and utterly undetectable.
